STEPHEN V. DILLON, O'F BUTLER, PENNSYLVANIA, ASSIGNOR TO THE DILLONSAFETY RAZOR 00., A CORPORATION OF DELAWARE,

SAFETY-RAZOR.

Specification of Letters Patent.

Patented Apr. 16, 1912.

Application filed January 30, 1911. Serial No. 605,571.

citizen of the United States, residing at.

Butler, in the county of Butler and State of Pennsylvania, have inventedcertain new and useful Improvements in Safety-Razors;

and I do declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in safety razors.

One object of the invention is to provide a safety razor having animproved construction and arrangement of blade adjusting mechanismwhereby the blade may be adjusted for shaving more or less closely.

Another object is to provide a bladeadjusting mechanism which may bereadily swung to an out-of-the-way position to permit the stropping ofthe blade.

In the accompanying drawings Figure 1 is a side view of a safety razorconstructed in accordance with my invention. Fig. 2 is a bottom planview thereof; and, Fig. 3 is an end view. Fig. 4 is a central verticallongitudinal section. Fig. 5 is a detail horizontal section on the line55 of Fig. 1. Fig. 6 is a detail perspective view of the bolt for theblade adjusting mechanism.

Referring more particularly to the drawings 1 dentotes the blade holdingframe of the razor, said frame comprising side plates 2 connectedtogether at their rear edges by a transversely disposed handle attachingplate 3 and having on their front edges forwardly extending bearing lugs4 The lower ends of the side plates 2 are connected together by anintegral guard plate 5 having on its lower edge a series of rearwardlycurved comb teeth 6.'

To the rear plate 3 is secured a rearwardly projecting handle 7 which ispreferably in the form of a cylindrical tube and is provided on aportion of its length with a checkered surface 8 whereby a firm grip maybe obtained thereon. The inner end of the handle has formed thereonattaching lugs 9 which are riveted or otherwise secured to the rearplate 3 of the frame 1. Revolubly mounted within the bearing lugs 4 ofthe side plates of the frame is a blade supporting shaft 10, on which isfixedly secured a plate clamping member 11 which may be of any suitableconstruction to receive the inner portion of the blade 12 whereby thelatter is firmly held in place. In the blade 12 is formed a centrallydisposed aperture 13, the purpose of which-will be hereinafterdescribed. I

Revolubly mounted in the bearing lugs 24 of the side plates 2,immediately in the rear of the shaft 10, is a strop engaging,

roller 14:. Revolubly mounted in the upper and lower portion of the sideplates 2 are strop engaging rollers 15 and 16. When the strop is engagedwith the razor for the purpose of stropping the blade, the strop isinserted between the rollers 15 and 16 and,

the roller lt said rollers thus frictionally engaging the opposite sidesof the strop as indicated in dotted lines in Fig. 1 of the drawings.When thus engaged the razor frame is reciprocated back and forth wherebythe frictional engagement of the strop with the rollers will revolve thesame first in one direction and then the other. On one end of the shaft10 and the pintle of the roller 14: are fixedly mounted intermeshingspur gears 17 and 18 by means of which the movement of the roller 14:when engaged with the strop, will be imparted to the shaft 10 to swingthe blade clamping member 11 and the blade 12 back and forth, thus en:gaging first one side and then the other of the blade with the strop.

In order to provide for the adjustment of the blade and cause the sameto shave more or less closely, I providea blade adjustingmechanism'comprising a pair of curved arms 19 which are pivotallyconnected at their inner ends with the outer sides of the side plates 2as clearlyshown in Fig. l of the drawings. The lower upwardly curvedends of the arms 19 are connected together by an inwardly curved,integrally formed plate 20. The lower portion of the platev 20 ispreferably tapered to an edge as shown. The plate 20 is drawn intofrictional engagement with the edge of the blade and said edge therebysprung into more or less close engagement with the toothed lower end ofthe guard 5 by means of an adjusting bolt 21 having a loose connectionwith the plate 20. This connection comprises a stud 22 having on itsinner end a pair of apertured lugs between which is pivotally connectedthe flattened outer end of the bolt as shown. The inner end of the boltis tened to the rear side of the guard 'plate 5 by screws 28 or othersuitable fastening devices. The nut 25 whenthus arrangedwill berevolublysecured to the guard plate and adapted to be turned in onedirection or the other and thus screwing the bolt 21' inwardly oroutwardly whereby the latter will actuate the adjusting plate 20 todrawthe edge ofthe blade into more or less'close engagement wit-h thetoothed edge of the guard-plate.

When it is desired to-stropthe blade the nut 25' is turned to screw thebolt 21 entirely; out of engagement therewith, thus permittingtheblade'adjusting arms 1'9'and plate 20 to be swung upwardly andrearwardly onto the handle 8' as shown in'dotted lines inFig. 1 of thedrawings in which position said blade adjusting parts will be out of theway and prevented from interfering with the operation of'the strop.

From the-foregoing description taken in connection with the accompanyingdrawin'gs the construction and operation of the invention will bereadily understood without requiring-a more extended explanation.

Various changesin the form,proportion and the minor det-ails'ofconstruction may be resorted to'without' departing from the principle orsacrificing any of the advantages of" the claimed invention as definedinmember-into engagement with'the edge of the blade whereby the latter issprung into copieso: this patent maybe obtained for five cents each,b'yaddre'ssing'the Commissioner of 1 mm,-

more or less close engagement with the guard. v

2. In a safety razor, a frame, a pivot-ally mounted blade holdingmember, a blade secured therein, a blade adjusting member adapted tohold said blade in operative engagement with said guard, said adjustingmember'comprising a pair of curved arms pivotally connected attheirupper ends to said frame, a curved plate formed between the lower endsof said arms, an adjustingv bolt loosely engaged in saidplate, arevolubly mounted nut adapted to receive the threaded end of said boltwhereby the latter is actuated to 'draw' saidadj'usting plates gintoforcible engagement with the edge of jthe blade whereby the latter issprung into lmore or less close engagement with said 3 guard.

3. In a safety razor, a frame,- a toothed guard formed thereon andhaving formed therein avpass'age, a blade holdingmember pivotallymounted in said frame, a blade seouredin said-holdingmember, said bladehaving for'medtherein an aperture, a blade adjusting member, said membercomprising a pair'of curved arms pivotally connected at their-outer endsto'said frame, a curved plate formed between the lower ends of saidarms, said plate being tapered toward its lower edge',;a stud arrangedin saidplate, an adjusting bolthingedly connected to said stud, saidbolt having a threaded inner end,

adapted to project through the passage in said guard plate, a recessednut" attaching plate secured to the rear side of said guard plate, a nuthaving a revoluble engagement with said attaching plate and adapted toreceive said threaded end of the bolt whereby the latter is screwedinwardly or outwardly, thus actuating-said blade adjusting member,whereby the edge of the blade is sprung into more or less closeengagement with said-guard Intestimony whereof I have hereunto set myhand in presence of two subscribing witnesses.
